Supply unit and liquid discharging apparatus

Abstract

A supply unit in which a liquid container including a coupling portion being detachably mounted includes: a liquid introduction unit coupled to the coupling portion of the liquid container; an urging member that urges the liquid container in an uncoupling direction which is a direction opposite to a coupling direction, the coupling direction being a direction in which the liquid container is coupled to the liquid introduction unit; and an engagement lever having an engaging portion that engages with the liquid container when the liquid container is coupled to the liquid introduction unit, the engagement lever includes an operating portion operated by a user and a pressing portion configured to press the liquid container and is configured to release the engagement of the engaging portion with the liquid container when the operating portion is operated and to press the liquid container in the uncoupling direction by the pressing portion.

What is claimed is: 
     
       1. A supply unit in which a liquid container including a coupling portion having elasticity is detachably mounted, comprising:
 a liquid introduction unit coupled to the coupling portion of the liquid container; 
 an urging member that urges the liquid container in an uncoupling direction which is a direction opposite to a coupling direction, the coupling direction being a direction in which the liquid container is coupled to the liquid introduction unit; and 
 an engagement lever having an engaging portion that engages with the liquid container when the liquid container is coupled to the liquid introduction unit, wherein 
 the engagement lever includes an operating portion configured to be displaced by an operation of a user and a pressing portion configured to press the liquid container, and 
 due to a displacement of the operating portion from a stopping position to an operation position, the engagement lever is configured to release engagement of the engaging portion with the liquid container and to press the liquid container in the uncoupling direction by the pressing portion. 
 
     
     
       2. The supply unit according to  claim 1 , wherein
 the engaging portion, the operating portion, and the pressing portion are configured to rotate about a first rotation shaft, and 
 a distance from the first rotation shaft to the operating portion is longer than a distance from the first rotation shaft to the pressing portion. 
 
     
     
       3. The supply unit according to  claim 1 , wherein
 a distance of movement in the uncoupling direction of the liquid container pressed by the pressing portion is shorter than a distance of movement in the uncoupling direction of the liquid container urged by the urging member. 
 
     
     
       4. The supply unit according to  claim 1 , further comprising
 a mounting section in which the liquid container is to be mounted, wherein 
 an insertion opening for inserting the liquid container is formed in the mounting section, and 
 the engagement lever is arranged so that the operating portion is located outside the insertion opening. 
 
     
     
       5. The supply unit according to  claim 1 , further comprising
 a support member that supports the liquid container, wherein 
 the urging member urges the liquid container through the support member, and 
 the pressing portion presses the liquid container through the support member. 
 
     
     
       6. The supply unit according to  claim 5 , wherein
 the support member is configured to rotate about a second rotation shaft, which intersects the coupling direction, between a first position and a second position that is located in the coupling direction relative to the first position, 
 the liquid container is guided to a predetermined position on the support member along a guide path, which intersects both the coupling direction and the second rotation shaft, in a state where the support member is located at the first position, and 
 the liquid introduction unit is coupled to the liquid container by the support member rotating, in a state where the liquid container is located at the predetermined position, from the first position to the second position. 
 
     
     
       7. The supply unit according to  claim 6 , wherein
 the liquid introduction unit is arranged in an inclined posture with respect to the guide path. 
 
     
     
       8. A liquid discharging apparatus comprising:
 the supply unit according to  claim 1 ; and 
 a liquid discharging head that discharges a liquid supplied from the supply unit to a medium.
